RADIATING ATTACHMENT FOR STOVEPIPES.

SPECIFICATION forming part of Letters Patent No. 578,102, dated March 2,1897.

Application filed November 14, 1895. Serial No. 568,928. (No model.)

My invention consists of a radiator attach` ment for a stovepipeprovided with a jacket adapted to carry heated air into differentcompartments, the construction and operation of which will behereinafter described.

It also consists of the combination and arrangement of parts hereinafterset forth.

Figure 1 represents a partial vertical section and partial sideelevation of a radiating attachment forastovepipe embodying myinvention. Fig. 2 represents avertical section of a portion detachedfrom Fig. 1 on an enlarged scale. Fig. 3 represents a horizontal sectionon line a; Fig. 2. Fig. 4 represents a side elevation of the registershown in Fig. 1 on an enlarged scale.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A designates a drum, which is connected attop and bottom with thesections B and C of a stovepipe, said drum havingconnected with the walls thereof the horizontal fiues D, which in thepresent case extend in series at a right angle to each other, each iiuebeing connected with the wall of the drum, so as to be open to theatmosphere, but not in communication with the interior of the drum.4

It will be seen that the iiuesD provide the drum with additionalheating-surfaces, and they also heat the air contained in the same, thehot air being discharged into the apartment in which the drum islocated, thus providing a convenient, inexpensive, and efficientradiator in'connection with the stovepipe. By having the iiues arrangedat angles to each other, instead of in parallel linesone above theother, the products of combustion,

which would otherwise pass upward parallel to the sides of the flues,and thus escape into the upper pipe, are deflected to the rightand leftand come in contact with the flues in the alternate rows, therebyheating the series of pipes and thus utilizing to a great extent theproducts of combustion, which otherwise simply heat the stovepipe. Atthe top of the drum is a flanged annulus E, the same being secured tothe wall of the drum and receiving the pipe-section B.

The lower end of the drum has connected with it the flanged annulus F,which has an outer flange to receive the pipe-section O, a projectingshoulder F', against which the inner end of said pipe abuts, and aninner flange F2, by which provision the drum is firmly connected withsaid sections and sustained steady in position.

When it is desired to convey the heat to another apartment, say oneabove the drum, I employ the jacket G, which incloses the drum andportions of the stovepipe above the same and is open at bottom, so thatair may be admitted into said jacket and be heated by said drum andcommingle with the heat of the air radiated from the iiues D of thelatter, so that a large body of heated air may be directed into saidapartment, as will be shown in Fig. 4. Should it be desired to directthe heated air into the apartment containing said drum, I provide thejacket G with the register H, the eifect of which is evident.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A drum with air-fines therein, annuli connected with the ends of `saiddrum, pipes connected with said annuli, a jacket open at bottomsurrounding said drum, and a portion of the pipe above the same, and aregisterin said jacket.
